Competitor Comparisons

A source-available invoice, quote, project and time-tracking app built with Laravel

Pros of Invoice Ninja

  • More extensive feature set, including advanced invoicing, client management, and payment integrations
  • Larger and more active community, with frequent updates and contributions
  • Better documentation and support resources

Cons of Invoice Ninja

  • More complex codebase, potentially harder to customize or extend
  • Heavier resource requirements due to its comprehensive feature set
  • Steeper learning curve for new users and developers

Code Comparison

Invoice Ninja (Laravel-based):

public function index()
{
    $data = $this->invoiceRepo->getDatatable(Auth::user()->account_id);
    return $this->returnDatatable($data);
}

Crater (Vue.js-based):

async fetchInvoices({ commit, state }) {
    const { data } = await invoiceAxios.get(`/api/v1/invoices`, {
        params: state.invoiceFilters
    })
    commit('SET_INVOICES', data.invoices)
}

Both projects use modern frameworks, but Invoice Ninja's backend is primarily PHP/Laravel, while Crater focuses on a Vue.js frontend with a Laravel API. Invoice Ninja's codebase is more extensive, reflecting its broader feature set, while Crater's code is more focused on simplicity and ease of use.

Online Accounting Software

Pros of Akaunting

  • More comprehensive feature set, including inventory management and project tracking
  • Larger community and more frequent updates
  • Multi-currency support out of the box

Cons of Akaunting

  • Steeper learning curve due to more complex functionality
  • Potentially overwhelming for small businesses with simpler needs
  • Heavier resource usage, which may impact performance on lower-end servers

Code Comparison

Akaunting (Laravel-based routing):

Route::group(['middleware' => 'auth'], function () {
    Route::get('invoices', 'InvoiceController@index');
    Route::post('invoices', 'InvoiceController@store');
    Route::get('invoices/{invoice}', 'InvoiceController@show');
});

Crater (Vue.js component structure):

<template>
  <div class="invoice-list">
    <invoice-table :invoices="invoices"></invoice-table>
  </div>
</template>

<script>
export default {
  // Component logic
}
</script>

Both projects use modern web technologies, but Akaunting follows a more traditional MVC structure with Laravel, while Crater leverages Vue.js for a more component-based approach. This difference in architecture may influence the choice depending on the development team's expertise and project requirements.

A self-hosted open source application for managing your invoices, clients and payments.

Pros of InvoicePlane

  • More established project with a larger community and longer history
  • Offers a wider range of features and customization options
  • Supports multiple languages and currencies out of the box

Cons of InvoicePlane

  • Older technology stack (CodeIgniter 3) compared to Crater's modern Laravel framework
  • Less frequent updates and potentially slower development cycle
  • User interface may feel less modern and intuitive compared to Crater

Code Comparison

InvoicePlane (PHP):

public function get_quote_total($quote_id)
{
    $this->load->model('quotes/mdl_quote_items');
    $this->load->model('quotes/mdl_quote_tax_rates');
    $this->load->model('quotes/mdl_quote_amounts');

    $quote_total = $this->mdl_quote_amounts->quote_amount_sum($quote_id);
    return $quote_total->quote_total;
}

Crater (PHP):

public function getInvoiceTotal($invoice)
{
    return $invoice->items->sum(function ($item) {
        return $item->total;
    }) + $invoice->tax;
}

The code comparison shows that Crater uses more modern PHP syntax and Laravel's collection methods, resulting in more concise and readable code compared to InvoicePlane's approach.

ERP beyond your fridge - Grocy is a web-based self-hosted groceries & household management solution for your home

Pros of grocy

  • More comprehensive household management features (including meal planning, chores, and battery tracking)
  • Larger and more active community with frequent updates and contributions
  • Self-hosted solution offering greater privacy and control over data

Cons of grocy

  • Steeper learning curve due to more complex features and options
  • Less focus on invoicing and financial management compared to Crater
  • May be overkill for users primarily seeking invoice management

Code comparison

Grocy (PHP):

public function getProductDetails(\Grocy\Objects\Product $product)
{
    $stockCurrentRow = $this->getDatabase()->products_current_stock()->where('product_id = :1', $product->id)->fetch();
    $stockAmount = $stockCurrentRow !== null ? $stockCurrentRow->amount : 0;
    return ['stock_amount' => $stockAmount, 'last_purchased' => $product->last_purchased];
}

Crater (Laravel/PHP):

public function getInvoiceDetails(Invoice $invoice)
{
    $items = $invoice->items()->with('taxes')->get();
    $total = $items->sum('total');
    return ['items' => $items, 'total' => $total, 'due_date' => $invoice->due_date];
}

Both projects use PHP, but Grocy focuses on inventory management while Crater emphasizes invoicing functionality. The code snippets reflect these different priorities in their respective domains.
